Folding full-motion horizontal tail mechanism

Abstract

The invention provides a folding full-motion horizontal tail mechanism, and belongs to the technical field of folding-wing unmanned aircrafts. The mechanism comprises a left horizontal tail, a left turntable, a horizontal tail connection body, a right turntable, a right horizontal tail, torsional spring covers, a pressing screw, torsional springs, horizontal tail rotating shafts and a locking mechanism, wherein two rotating shaft mounting holes which are symmetric in the transverse direction are formed in the horizontal tail connection body; an included angle between the axis of each mounting hole and the horizontal plane is 55.5 degrees; after the horizontal tail connection body is fixedly connected with the left turntable and the right turntable, the rear end face of the horizontal tail connection body and the rear end face of a machine body form a 45-degree angle; rotating shaft mounting sleeves matched with the horizontal tail rotating shafts are arranged on the left horizontal tail and the right horizontal tail; included angles between the central axis of each rotating shaft mounting sleeve and the wing plane as well as between the central axis of each rotating shaft mounting sleeve and the wing chord direction are 45 degrees; the torsional springs are arranged on the horizontal tail rotating shafts; and the locking mechanism makes the horizontal tail rotating shafts rotate by 105 degrees and locks the horizontal tail rotating shafts, so that the horizontal tails rotate to a position vertical to the side face of the machine body from the position close to the side face of the machine body. The mechanism is connected reliably, has a simple structure, and is unfolded quickly and operated easily.

Description

technical field [0001] The invention relates to a folding wing of an unmanned aerial vehicle, in particular to a folding full-motion horizontal tail mechanism, which belongs to the technical field of folding wing unmanned aerial vehicle structures. Background technique [0002] An unmanned aerial vehicle is an unmanned aerial vehicle controlled by a radio remote control device or an onboard computer program control system. Unmanned aerial vehicles are simple in structure and low in use cost. They can not only complete the tasks performed by manned aircraft, but also are suitable for tasks that manned aircraft are not suitable for, such as reconnaissance in dangerous areas, air rescue command and remote sensing monitoring. [0003] There are three main applications in the market today: fixed-wing unmanned aerial vehicles, unmanned helicopters and unmanned airships. Compared with these mature unmanned aerial vehicles, the biggest advantage of folding-wing unmanned aerial vehic...

Problems solved by technology

[0003] There are three main applications in the market today: fixed-wing UAVs, unmanned helicopters and unmanned airships. Compared with these mature UAVs, the biggest advantage of folding-wing UAVs is that they save space and are convenient Carrying and transportation greatly improves the convenience of unmanned aerial vehicles, but because its research started late and the technology is relatively complicated, it is basically still in a blank state in the current commercial market application
